Encouraging people to show up
We played a FG-Con game this evening and only 2 out of 5 people showed up. One of the players said that his previous game had failed because of the same problem. Any ideas on encouraging people to keep to their commitment? We discussed how paid games, where you pay a small token amount at the beginning of a long campaign, can help filter out people who don't take the game seriously. But is there anything else anyone's doing, particularly for one-shots where the commitment seems to be even lower?
